A machinist turns the power on to a grinding wheel, at rest, at time t = 0 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of The wheel is run at that angular velocity for 36 s and then power is shut off. The wheel slows down uniformly at until the wheel stops. In this situation, the average angular acceleration in the time interval from to s is closest to:
